3.2        Experience has shown that 15% of municipal rates bills contain an estimated amount for electricity usage. We randomly select a sample of 75 rates bills.

3.2.1     Compute the standard error.

3.2.2     What is the probability that less than 14% of the bills in the sample will contain an estimated amount for electricity usage? Interpret your answer.

Experience has shown that the weight of oranges produced by an orchard in Tzaneen is normally distributed, with an average weight (μ) of 120g and a standard deviation (σ) of 20g. A sample of 115 of these oranges is randomly selected. a) Determine the standard error for this sample. (3) b) What is the probability that the mean weight of the oranges in the sample lies between 118g and 121.5g? Interpret your answer

In an article in the Journal of Management, Joseph Martocchio studied and estimated the costs of employee absences. Based on a sample of 176 blue-collar workers, Martocchio estimated that the mean amount of paid time lost during a three-month period was 1.3 days per employee with a standard deviation of 1.9 days. Martocchio also estimated that the mean amount of unpaid time lost during a three-month period was 1.4 day per employee with a standard deviation of 1.8 days. Suppose...

Experience has shown that 30% of all persons afflicted by a certain illness will recover with the standard treatment that is available. A drug company has developed a new therapy for this illness. Fifteen people with the illness are selected at random and treated with the new therapy. Eight of these fifteen recover from the illness. a. Suppose that the new therapy is as effective as the standard treatment. Under this assumption, what is the probability that 8 or more...

The Office of Student Services at a large western state university maintains information on the study habits of its full-time students. Their studies indicate that the mean amount of time undergraduate students study per week is 15 hours. The hours studied follows the normal distribution with a standard deviation of 15 hours. Suppose we select a random sample of 100 current students. What is the probability that the mean of this sample is less than 14 hours?

(a) On average, how many ounces of jelly beans are there in a bag? What is the standard deviation? (b) Assuming that the claim of the company is true, what is the probability that a randomly selected bag contains less than 16.25 ounces? c) A consumer watch group wants to investigate the...

Suppose that we will randomly select a sample of 79 measurements from a population having a mean equal to 21 and a standard deviation equal to 8. (a) Describe the shape of the sampling distribution of the sample mean . Do we need to make any assumptions about the shape of the population? Why or why not? Normally distributed ; yes , because the sample size is large . (b) Find the mean and the standard deviation of the sampling...

Please answer ALL questions on page: 1. Cognitive science consistently shows that one of the most effective studying tools is to self - test. A recent study reinforced this finding. In the study, 118 college students stu died 48 pairs of Swahili and English words. All students had an initial study time and then three blocks of practice time. During the practice time, half the students studied the words by reading them side by side, while the other half gave...
